ASME/ANSI B18.1.3M:1983 Metric Round Head Rivet adopts a metric round head rivet design under ASME/ANSI specifications to meet the needs of permanent joints requiring metric rivet compatibility.
The round head creates a smooth bearing area on the exposed surface, and the deformed shank produces a stable connection where threaded fasteners are unsuitable or loosening is undesirable. Its advantages lie in a clear installation method, well-defined load path, and good adaptability across different materials and installation spaces.
This product is suitable for export equipment, sheet metal joints, metal accessories, industrial housings, and repair production. Material, shank diameter, head size, and corrosion-resistant finish can be adjusted for the final application, balancing cost control, corrosion protection, and assembly consistency.
